K7S5A and MBM5

I have a k7s5a and I recently installed MotherBoardMonitor5 on the comp that has the k7s5a and heres what I did.

I set temp. sensor 1 to Sis950/ITE8705F-1 and I get 32 degrees on it while typing this.

I set temp. sensor 2 to Sis950/ITE8705F-2 and I get 23 degrees on it while typing this.

I set temp. sensor 3 to Sis950/ITE8705F-3 and I get 37 degrees on it while typing this.

All the temps are in celcious(sp?) and my ambient temp is 19

My question is what are the different sensors and where on the board are they? Also I am using the stock AMD heatsink if it makes a difference.

The CPU temp is sensor 3 and the motherboard sensor is 2. 1 is not in use.

OK thanks
